i was listening to it this morning between 7:00am and 8:00am ET, it came up pretty strong for a short while and sounded like old radio mystery programs playing with well great sounding modulated audio within 10Khz bandwidth however, its right on the dot of 6770 Khz.
i suspect some type of crystal controlled tube transmitter with an output of 5 watts or less.
ive been checking out OTR every day at different times between 12/27 and today and have never seen the carrier disappear from the waterfall.
even at 3:00am ET i can see the carrier on the waterfall but thats it.
i have to wonder if this is intentionally done to provide some sort of "entertainment service" for an old friend that does not have a computer/internet to play this content.
